Effect of paclobutrazol and ethephon on leaf nutrient uptake in 'Allahabad safeda' guava (Psidium guajava L.) plants
2010
Brar, J.S.
The guava plants-treated with paclobutrazol (PBZ) and ethephon assimilated significantly higher N, P, Zn and Fe content in leaves. However, the leaf K concentration was reduced with PBZ treatments and improved with ethephon treatments. The concentration of all nutrients in the leaves of treated plants was recorded highest after fruit harvest in the month of October except P and Fe, which was recorded maximum in the month of August and September, respectively under ethephon treatments. The nutrient assimilation was significantly affected in all treated plants but PBZ particularly 1000ppm application markedly increased the overall nutrient assimilation.
